I always went with the game theory of, "if you can't beat their Turn 1, be faster than their turn 2." Unless you are not faster than say, 80% of the people on your server/cluster, this might hurt you in the long run, especially in sage. But in a more controlled atmosphere, say Space Time, it could be worth a shot. But if the power gap is just too huge, it won't matter what you do.

Also, if they use Kushina and are faster, your Kushina won't matter at all for obvious reasons (removes immunity, etc).
